By default, this value is 254.
Command Mode
LDP Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
If loop detection is enabled, the LDR ID that is in the path vector list of the label mapping message or the
label request message or the path vector length exceeds the maximum length, then it is deemed that a
loop occurs.
Example
This example shows how to configure the maximum path vector to 30.
Switch# configure terminal
Switch(config)# mpls ldp configuration
Switch(config-ldp)# path-vector maxlength 30
Warning: The configuring will lead to LDP sessions restart.
Switch(config-ldp)#
67-28 ping mpls ipv4
This command is used to check the connectivity of the LSP for the specified FEC.
ping mpls ipv4 NETWORK-PREFIX/PREFIX-LENGTH [repeat COUNT] [timeout SECONDS]
Parameters
NETWORK-PREFIX/PREFIX-
LENGTH
repeat COUNT
timeout SECONDS
Default
None.
Command Mode
User EXEC or Any Configuration Mode.
Command Default Level
Level: 1.
Usage Guideline
This command is used to check the connectivity of the LSP for the specified FEC. If there is no LSP for
the specified FEC, the "Destination unreachable" message will be displayed. Otherwise, MPLS echo
request messages will be sent out to along with the LSP of the specified FEC. If the egress LSR received
the request message, it will reply the request message sender with an MPLS echo reply message. If the
sender cannot receive replies before the timeout, the "Request timed out" message will be displayed.
Specifies the IPv4 prefix FEC whose LSP connectivity will be checked.
Specifies the number of times to send the same packet. This value
must be between 1 and 255. The default value is 4.
Specifies the interval in seconds to send the MPLS request packet.
This value must be between 1 and 99 seconds. The default value is 2
seconds.
